    Ag3PO4 and Ag3PO4/g-C3N4 were successfully synthesized by an in-situ solvothermal method using graphitic carbon nitride obtained by sectional heating of guanidine carbonate and AgNO3 as starting materials. The composites were characterized by XRD, SEM, PL, DRS and BET. The photocatalytic performance was determined by deNOx reaction under different light wavelength irradiation. Ag3PO4/g-C3N4 composites with different ratio showed different band gap and morphology, and also decreased the photo-corrosion and self-corrosion by forming heterojunction. The photocatalytic deNOx ability of Ag3PO4/20%g-C3N4 was 15.52% under irradiation of visible light (>400 nm) and could be enhanced to 41.76% under irradiation of 290 nm. With the increment of the g-C3N4 content, high efficiency of charge separation induced by the formation of heterojunction between Ag3PO4 and g-C3N4.
